The 2021 GMC Terrain comes to you this year with luxury and sophistication. A spacious interior features high quality material and plenty of room throughout the cabin for all passengers and their gear. With a choice of four trim levels and two powertrain options, this well-equipped compact SUV is a refined ride at an affordable price tag.


The Terrain gives you the choice of four trim levels, adding more features to each trim.

  • SL, $25,000 – equipped with an array of technology and safety features including the Pro Safety package.
  • SLE, $28,400 – Pro Safety Plus package available, remote start is an option for an added $295 and a rear-seat entertainment system with DVD player is available for $1,995
  • SLT, $31,200 – available larger alloy wheels, added sunroof for an additional $1,495
  • Denali, $38,300 – Adds Pro Safety Plus suite of driver aids and a larger engine.


There are two turbocharged four-cylinder engines in the Terrain. The standard engine that comes in most trims performs well in city driving, but struggles at higher speeds and accelerating. The other engine option is strong enough for most driving, but you must buy the Denali trim to get it.

  • 1.5-liter inline-four, 170-horsepower
  • 2.0-liter turbo-four that puts out 252-horsepower (Denali trim)

Both engines are paired with a nine-speed automatic transmission and handle smoothly over rough payment, around corners, and through city streets. More power is added to the Denali trim, with the 2.0-liter turbo-four.

2021 GMC Terrain on the Road

SL trim features front-wheel drive and SLE trims and above offer all-wheel drive as an available option.

Towing capabilities reach 3,500 pounds when properly equipped with the 2.0-liter turbo-four engine, delivering 252 hp and 260 pounds of torque.

Estimated gas mileage for the base engine front-wheel drive is 25/30 mpg in the city/highway. The larger engine is estimated at 22/28 mpg city/highway with FWD and 21/26 mpg with AWD.


All GMC Terrains make an impression with its bold grille and signature C-shape design headlamps. Engineered to stand out, the standard LED headlamps help cut through the darkness and the halogen fog lamps help illuminate the road in foggy conditions. This same lighting design in the front flows to the back in its tail lamps. The Denali trim elevates the Terrain’s style with its proprietary accents and features.

The 2021 GMC Terrain is a solid SUV, but there are some things to consider. It offers plenty of space throughout its cabin and a long list of features with a smooth ride. It falls short in cargo capacity and acceleration with its standard engine, and so if you want the extra power you’ll have to move up to pricey Denali to get it.
